Question :
Discuss the anatomy structure of T.S Dicot Root?
Answer :
The cells in T.S. appear polygon, and are thick walled. The protoxylem lies towards the periphery, so the xylem is called exarch. The protoxylem vessels bear annular and spiral thickenings while metaxylem vessels have reticulate and pitted thickenings.
